CHARLES M. BURGESS, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE RUSSELL& ERWIN MANUFACTURING COMPANY, OF SAME PLACE.

TRANSOM-LIFTER.

SPECIFICATION forming part of Letters Patent No. 512,275, dated January9, 1894.

Application filed August 23, 1393- Serial No. 483,375- (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES M. BURGESS, a citizen of the United States,residingat New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inTransom- Lifters, of which the following is a specification.

My invention relates to improvements in transom lifters, and the objectsof my improvements are simplicity and economy in construction andconvenience and efficiency in operation.

In the accompanying drawings; Figure 1 is a front elevation of mytransom lifter, together with a portion of the transom and casing. Fig.2 is a side elevation of the same. Fig.3 is a detached view of thefastening device. Fig. 4 is a section of the same on the line as 00 ofFig. 3, together with the lifting rod; and Fig. 5 is asection thereof onthe line y y of Fig. 3, the central parts being shown in elevation.Figs. 3, 4 and 5 are on an enlarged scale.

A designates the transom and B the casing by its side. The transombracket 6 is connected by means of the link 7 with the transom rod C,the crank arm of said link being received in the eye 8. This eye isformed by a multiple coil in the transom rod, whereby the endsprojecting above and below said eye are spread apart laterally, and whensupported in the bracket eyes 9, with the crank arm of the link in theeye 8, said rod will be held without any liability of its turning overand working out of place.

The fastening device for holding the rod in different positions consistsof a case or frame D and a spiral spring 10 with its ends turnedoutwardly to form the handles 11. The case D is formed with a verticalopening through which the lifting rod C extends, and openings on itsfront through which the handles or arms 11 extend as shown. The springis wound of a size which will firmly embrace the rod and adhere theretoby friction, excepting when the arms or handles 11 are compressed tounwind the coils of the spring and open it. The parts are arrangedin theposition shown and in this position the friction of the spring upon therod is sufficient to firmly lock the rod in place against being movedeither up or down. By pressing the arms orhandles 11 toward each other,the coils of the spring are unwound sufficiently to permit the rod toslide freely up or down therethrough for operating the transom.

By my improvements, I form an efficient and operative lifting rodand'the eye for the link in one piece of wire, whereby an efficient rodis formed at a small cost. The holding or fastening device is also of avery simple and inexpensive construction, is very easily andconveniently operated and efficiently locks the rod in place.

While I prefer and undoubtedly will employ both of these improvements ina single transom lifter, it is evident that either one of them could beused in a transom without the employment of the other, the holdingdevice operating the same on transom rods in general that it does uponthe particular rod herein shown.

I claim as my invention-- l. The herein described transom lifter havingthe eye 80f the rod C formed in multiple coils and the link connectedtherewith by its crank arm extending through said eye, substantially asdescribed and for the purpose specified.

2. The fastening device for a transom lifter, consisting of the spiralspring having projecting handles or arms, and a suitable case forconfining said spring and arms with the rod extending through the coilsthereof, substantially as described and for the purpose specifled.

CHARLES M. BURGESS.
